Postcrossing

Okay, first of all, I am not gay.  I was messing around on another website and saw something called postcrossing.  The curiosity got the better of me and I googled it.  Basically you sign up for free.  Then you have to send a post card to someone on the site and when they receive it,  someone else sends you a post card.  So basically you send and receive postcards from people all over the world.  I thought it was an interesting idea and mentioned it to the geography teacher here at school.  Thought she might be able to use it in her classroom.  Thought somebody on here might be interested in trying it also.
